What are the Types of Bearing Lubrication?

● What are the types of liquid lubricants?

Liquid lubricants are mineral oil (mechanical oil and various special oils), synthetic oil (grease oil, silicone oil, synthetic hydrocarbon, polyethylene, etc.) animal and vegetable oil (butter, vegetable oil, etc.) and aqueous liquid (emulsion, microemulsion and synthetic liquid, etc.).

● What are the types of semi-solid lubricants?

According to the nature of thickening agent: hydrocarbon-based grease, soap-based grease, organic grease and inorganic grease.

Soap-based grease is the most widely used in rolling bearings. Soap grease can be divided into single soap grease (such as calcium grease, sodium grease, lithium grease, aluminum grease, barium grease and lead grease, etc.), mixed soap grease (such as calcium sodium grease, aluminum calcium grease, lithium calcium grease, etc.), compound soap grease (compound calcium grease, compound lithium grease, compound lead grease, compound barium grease and compound lithium Calcium grease, etc.).

● What are the characteristics of solid lubrication?

Solid lubrication is in the use of oil lubrication or grease lubrication can not reach or can not meet some specific working conditions (such as high temperature, high vacuum environment and do not allow pollution of food machinery and pharmaceutical machinery, etc.) requirements, can be used when the lubrication method. The characteristics of solid lubrication is to avoid the leakage of oil lubrication or grease lubrication and other phenomena, do not need to set up oil supply facilities, manufacturing and use of lower costs. However, solid lubrication also has a high coefficient of friction, no cooling effect and short service life and other disadvantages.
